There are two types of hyperhidrosis: primary hyperhidrosis, also known as focal hyperhydrosis, and secondary hyperhidrosis, also known as generalized hyperhidrosis, notes WebMD. With the first condition, a person experiences sweating in the hands, underarms, face and feet. Unfortunately, there is no known reason for this sweating. The second form is usually linked to an underlying medical condition such as diabetes, obesity or Parkinson's disease.

Hyperhidrosis is an embarrassing, undesirable condition. It affects approximately 3 percent of the world population, states the International Hyperhidrosis Society website. A person's body contains somewhere between 2 million and 4 million total sweat glands. The specific gland related to hyperhidrosis is the eccrine sweat gland. With hyperhidrosis, these sweat glands become overly stimulated. In most cases, a person diagnosed has to change clothes and apply deodorant more frequently than normal. Fortunately, there are known remedies, which include various antiperspirants, surgery and medications. In addition, the International Hyperhidrosis Society is consistently raising awareness of the disease, its website states.
